Abstract
Disclosed herein is a superabsorbent polymer with a surface crosslinked with a water-soluble polyvalent cationic salt, a polycarbonic acid-based copolymer, and a surface crosslinking agent wherein an improvement is brought about in physical properties, with the concomitant reduction of process time and cost. Also, a method is provided for preparing the surface-crosslinked superabsorbent polymer.
